Railway guide device and rail-road vehicle

Abstract

The invention provides a railway guide device and a rail-road vehicle. The railway guide device comprises an upper revolving seat, a lower revolving seat and liftable guide wheels, wherein a bearing is arranged between the upper revolving seat and the lower revolving seat, a reset plate which extends downward is arranged at the bottom of the upper revolving seat, a plurality of rubber blocks are arranged on the lower revolving seat, a plurality of rubber blocks are symmetrically distributed on the two sides of the reset plate, the reset plate is clamped among the rubber blocks, and the guide wheels are mounted on the lower revolving seat. The curve passage capacity and the universality of the railway guide device are improved.

Description

technical field [0001] The invention relates to a railway and highway vehicle, in particular to a railway guiding device and a railway and highway vehicle. Background technique [0002] At present, the dual-purpose vehicle for railway and highway is widely used in the rail transportation industry because it can run on both the road and the railway. Railway and highway vehicles are usually used for railway traction, emergency repair, construction and emergency rescue operations. The railway and highway vehicles in the prior art are mainly improved on the basis of existing automobiles, and can be used on railways by adding railway guides , Chinese Patent No. 201210554322.1 discloses a guide wheel mechanism and a dual-purpose railway and road vehicle, wherein the guide wheel mechanism includes components such as a guide wheel, an oil cylinder and an oil cylinder frame, and the guide wheel is driven by the oil cylinder to realize lifting, and the guide wheel mechanism is fixed b...

AI Technical Summary

Problems solved by technology

However, in actual use, when a dual-purpose vehicle for railway and highway passes through a curve on the rails, it is limited by its own structural form and connection mode, so the requirements for the turning radius of the curve are relatively large, and the minimum curve radius of the railway that can pass is 35m, unable to meet the requirements of 25m curved lines in subway and tram depots, resulting in poor curve passing ability and versatility of railway guide devices in the prior art
